[Also in Group XXII] A stamping press comprises a box-like frame A having a rectangular tool supporting surface 10, a first reciprocable die-carrying crosshead B spaced from said tool supporting surface, a second reciprocable crosshead C located within said frame and comprising a rectangular member, guide means on a plurality of the sides of said second crosshead and the frame, a plurality of members integrally connecting said first and second crossheads for movement as a unit, said members being spaced along and fixed to opposite sides of said crossheads with at least one of said members on each of said sides being positioned between two other such members on the same side, a plurality of parallel crankshafts rotatably supported on said frame intermediate said first and second crossheads, pitman means connecting said crankshafts to said second crosshead and means for rotating said crankshafts in timed relationship. The guide means for the second crosshead C comprises adjustable U-shaped members 11 attached to the frame each provided with spaced guideways 12, 121 which co-operate with grooves 15 in the crosshead. The driving mechanism for the crosshead C includes a pair of crankshafts 17, 18 driven in synchronism by a pair of gears 21, 22 which are driven through one revolution by mechanism (not shown) each time a pedal is depressed. Each crank 24 of the crankshafts is connected to the crosshead C by an adjustable pitman 25 locked in position by a member 37. The crosshead C is attached to the upper crosshead B by a plurality of rods 44 to 51 which project through the table 10 of the frame and are each guided by a split tapered sleeve 54 slidably supported in a tubular member 55 fixed on the table. The upper ends of the split tapered sleeves are in screw-thread engagement with a member 56 rotation of which adjusts the sleeves. Those portions of the rods extending between the upper crosshead and the table are provided with telescopic guides 57. The crosshead assembly is counterbalanced by springs 60 connecting the corners of the lower crosshead to the frame. The press is provided with shoots 70 and pivoted roll feed mechanism E for feeding strip to the dies between each working stroke of the press. The top feed rolls are lifted by arms 71 after feeding to leave the strip free to be located by pilots on the table. The rolls are rotated by an adjustable crank mechanism F connected to the crankshaft 17 which enables feeds of different lengths to be made.

Title: Burner apparatus
IPC: F23N5/00
Filed: 1976-03-05
Abstract: In the method of controlling gas, oil or coal-dust burners, the adaptation to different degrees of loading is carried out by changing the quantity of the fuel supplied, and the control of the corresponding air quantity is effected by means of a solid-state electrolytic oxygen detector which is arranged in the flue-gas duct. By means of this method, a simplification of the control and shortening of the regulating period are brought about so that optimum combustion conditions are achieved. There is moreover a reduction of the number of the regulation and control members as well as an increase in operating safety.

Title: Process for freezing soils by means of carbonic acid
IPC: E21D1/12
Filed: 1929-03-20
Abstract: 308,310. Dehottay, H. March 21, 1928, [Convention date]. Freezing the ground; foundations.-In sinking shafts or forming foundations &c. in water-bearing soil, the soil is frozen by the use of solid CO; which is produced in freezing tubes arranged in bore-holes. The tubes are connected to a vacuum pump which draws off CO2 gas and delivers it to a compressor where it is compressed and liquefied for return to the tubes and re-evaporation, solid CO2 being formed in the tubes; subsequently the solid is allowed to gasify. Preferably gasifying is effected in alternate bore-holes while intermediate bore-holes are being supplied with the solid. If freezing is to be more intense, or to be effected only, at pre-determined points, stoppers may be suspended below such points and the pipes supplying liquid CO2 are brought down near to such points. The Specification as open to inspection under Sect. 91 (3) (a) states also that the solid CO2 may be produced separately and inserted as blocks into the freezing tubes. This subject-matter does not appear in the Specification as accepted.
